diamond.exe is still required 20 years after, curiosity

I try create a cabinet file with quantum compression, using iexpress.exe. But It requires diamond.exe. It is not present on windows 10.

I not know all the story, seems that diamond.exe was renamed makecab.exe round 1997.Anyways: diamond.exe support quantum compression until version 1.00.0530 (03/29/95), version 1.00.0540 (02/01/96) removed the feature.
